I have owned my 2008 for a little over 2 years and at first I loved it but now I'm starting to have problems.
Feels like my transmission is slipping, if I'm at a dead stop when I press on the gas it is kinda hesitant (seems to only do this in the hot weather) When I run my ac it has less power, my back locks don't work. A year ago I had the reduce engine power show up but I let me car sit for the weekend and haven't had the message again (knock on wood)
I still have 3 years left on my lease and I'm starting to get worried. My first car I bought was a complete lemon thought I was doing the smart thing going to a "major dealership" but the warranty that you buy seems to not cover anything.
I love my Impala but if this keeps up I will straight go to FORD!!!
